Back to the original question concerning SC's

"Do you play SC's to a 3-bet when there will be 3 going to the flop or only if there is 4 going to the flop? What I am thinking now is since 90% of the time there is a continuation bet on the flop after a 3-bet with 3 going to the flop, I will need a strong heads-up hand AK-AJ, AA-TT to decide if I am going play the hand any further - not SC's.
